std::experi...::operator=(3)

okay bestie, we're on std::experi...::operator=(3) — the C++ Standard Library page for std::experimental::ranges::tagged's assignment ops. 🎀✨

💖 NAME 💖

The whole page is about std::experimental::ranges::tagged::operator= — and yes, the NAME section also lists std::experimental::ranges::tagged::operator= again. Double naming, double slay. 💅

✨ Synopsis ✨

          tagged &operator=( tagged&& that ) = default;
       (1)
          tagged &operator=( const tagged& that ) = default;
       (2)
          template< class Other >

              requires Assignable<Base&, Other>
       (3)
          constexpr tagged& operator=( ranges::tagged<Other, Tags...>&& that )

              noexcept(std::is_nothrow_assignable<Base&, Other>::value);
          template< class Other >

              requires Assignable<Base&, const Other&>
       (4)

          constexpr tagged& operator=( const ranges::tagged<Other, Tags...>&
       that );
          template< class U >

              requires Assignable<Base&, U> && !Same<std::decay_t<U>, tagged>
       (5)

          constexpr tagged& operator=( U&& that )
          noexcept(std::is_nothrow_assignable<Base&, U>::value);

🦋 the overloads, bestie 🦋

Assigns the contents of that to *this. No cap. 💖

• 1,2) — tagged has defaulted copy and move assignment operators that invoke the corresponding assignment operator of Base. yes, it's giving "delegate to Base" energy.
• 3) — Converting move assignment from a different tagged specialization with matching tags. Equivalent to static_cast<Base&>(*this) = static_cast<Other&&>(that);.
• 4) — Converting copy assignment from a different tagged specialization with matching tags. Equivalent to static_cast<Base&>(*this) = static_cast<const Other&>(that);.
• 5) — Assigns that to the Base subobject. Equivalent to static_cast<Base&>(*this) = std::forward<U>(that);.

🫶 Return value 🫶

*this. That's it. That's the return value. periodt. 💖
